Btrfs: make sure NODATACOW also gets NODATASUM set
A user reported hitting the BUG_ON() in btrfs_finished_ordered_io() where we had csums on a NOCOW extent. This can happen if we have NODATACOW set but not NODATASUM set, which can happen in two cases, either we mount with -o nodatacow and then write into preallocated space, or chattr +C a directory and move a file into that directory. Liu has fixed the move case in a different place, but this fixes the mount -o nodatacow case. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
